以CAT600阳离子交换树脂作为催化剂,醋酸酐既做溶剂又做乙酰化试剂,高效地进行了全乙酰基糖的合成。实验结果表明,所考察葡萄糖等8个糖类化合物在0.5 h内均能以较高的收率得到全乙酰基化的产物,产率达75%～95%。该方法具有高效、绿色、廉价、易于后处理等优点,有工业利用价值。 With CAT600 cation exchange resin as a catalyst, acetic anhydride acts as both a solvent and an acetylating reagent, and the synthesis of all-acetyl sugar is efficiently carried out. The experimental results showed that all the eight carbohydrates such as glucose and so on were able to get the product of acetylation with higher yield in 0.5 h with the yield of 75% -95%. The method has the advantages of high efficiency, green color, low price, easy post-processing and the like, and has industrial utilization value.
